To all 'whomz't may concern.'

Be it known that I, JOHN M. BENTON, a citizen of the United States, and a resident of Edgemont, in the county of Fall River and State of South Dakota, have invented a new and mprdved Motor Disk Plow, of which the following is a full, clear, and exact description. v

Among the principal objects which the present invention has in view are: to provide means for rotating the plowing disks employed in the invention independently of the progression of the plow; to provide means for rotating plowing disks at a variablespeed greater than the travel of the plow; to provide means on the plowing disks for crosscutting or grooving the bottom of furrows made by the disks; and to provide a simplified transmission mechanism whereby power is transmitted from an engine of suitable construction to plowing disks.

Reference is to be had tothe accompany ing drawingsl forming apart of this speci-l fication, in which similar characters oit'reference indicate corresponding parts in all the views, and in whieh- Figure l is a plan view of a plow conf structed and arranged in-accordancewitli the present invention; Fig. 2 is a side elevation of the same, as seen from the furrow sider of the plow; Fig-3 is a detail View showing the coupling driving belteniployed in the transmission mechanism; and Fig. 4 is a detail view, in cross section, of a modified construction of the plowing disk where is used a reinforcing back plate The plow disks 8 are cach suitably mounted upon a back 9. The back 9 is provided with a suitablehub 10, to receive a bearing bolt 11. 'l-liebolts 1l are each mounted in a bracket 12, ,whichbracket is extended from an angle beam 13 of theplow frame.

The plow traine is supported by a land wheel le, a furrow -wheel 15, and a caster wheel 16. The land and furrow wheels enumerated are each provided 'with a jack The frame is provided with a front or clevis bar 18, having .a suitable cle/vis 19 pivotally mounted thereon, to which the -draft team is hooked. As shown vin the ac- `Weighted iy-wheel 35.

form 20, upon which is me' 'nted an internal,

combustion engine The engine 21 i`s` by ateam of horses, or by a suitable tracn supplied from a'ga's or oil tank 22, and is cooled by a liquid normally carried in. a tank 23. To the driving siaft, 24' of the engine is coupled a short shaft 25 by means of'a knuckle 26. The shaft 25, knuckle 26,

and a sprocket wheel 27 tixedly mounted on said shaft 25, constitute what .may be termed members of the transmission mechanisni.

The 'transmission mechanism herein em-v ployed is provided to revolve shafts 28 and 29. The shafts 28 and 29 are suitably suspended in bearing brackets 30, and have each ixedly mounted thereon a pin wheel 31. The pins of the pin-wheels 3l engage `holes 32 formed in the disks 8 adjacent the periphery thereof. The holes 32 are eX- tended through the disks 8, and thus form free openings for the pins ot the wheels 3L to provide ample clearness therefor, and to avoid the accumulation of dirt and grit therein. i

. The shafts 28 and 29 are connected by means Aof a beltchain 33, to secure the necessary uniform rotation of said shafts. For this purpose, each shaft is provided with a sprocket wheel 34,'aboiit which the belt is passed, and with the sprockets whereof the links of the saidbelt engage. The wheels 34, as will be seen best in Fig. 1 of drawings, are vdisposed at'opposte sides of the wheel 27, andthe belt which extends between the wheels 34 also engages the teeth of the wheel 27.

To steady the operation of the mechanism, the engine 21 is provided with a suitable With a mechanism. thus constructed, it will be understood that when theenginev2l is operated, the shafts 28 and 29 lhive imparted thereto a uniform rotation, the speed ot which is regulated by .the speed of the engine, proportioned by the disks 8 bythe shat'ts 2S and 29, the disks in the present plow differ in the operation from disks .of ordinary coiistrnction'and employnient.v A prominent result of the increased eompanying4 drawings, the plow is drawn rotation of the disks 8 relative the rate of 110` progression of the plow is, that the disk-sl operate to pulverize the earth more perfectly, and to steady the operation of the plow, by relieving the sameof a lar e proportion of the-drift or pressure of t e furrow and caster wheels against the land side of the furrow. This action, it will be understood, willbe produced in disks having the usual sharpened and simplified cutting edge. It is the further purpose of ther invention, by the employment of the twisted teeth 36, vto groove the bottom of the furrow transversely. It will be noted by reference to Fig..l of the drawings that the teeth 36 are twisted to aline substantially with the plane of the land side of the furrow. It will be understood that the path followed by each tooth, when traversing the furrow, will be curved, as the result of the progression of the plow and ther rotation of the disk. lIn practice, the swath or groove cut or scraped by each of the teeth 36 is substantially transverse the line -of the furrow. It will be understood that, as the ,rotary speed of the disks 8 is increased,` the rearward inclinationof the groove cut by the teeth 36 will increase, and that as the speed of the diskv 8 is diminished, the angle of the groove cut by' the teeth 36 will be increased. It has been found that, by the emplo ment of a device of this character, where y the bottom of the furrow is grooved, Athe drainage or washing of t-he soi and the subsequent packing of the soil, to form a hard-pan, is materially lessened or avoided.

1 While I have herein illustrated and de- Y 'scribed the invention as appliedonly to the rotation' of the disks 8 by independent means,

such as the engine 21 carried on the frame of the plow, and whileI have indicated that the traction of the plow as an implement is eectedroraccomplished b means such as a horse team, it will be un erstood. that the natural operationcf the -disks will assist the traction ofthe implement, and under certain .conditions wil afford traction means'therefor. I do not, however deem thatdt is advisable to rely exclusively on the disk for the traction of the Elow, as certain lands, such 'as b or mars u would prove unsuitable or this purpose.

In the modified form of the invention shown in Fig. 4 of the drawin a back plate 37 is employed,lhaving holes 38, which structure more rigid.

Having thus described claim as newters Patent V- 1. A disk plow, comprising a wheel-carried frame; al plowing disk mounted on said frame 'and provided adjacent the periphery thereof with a series of equally-spaced holes; an engine mounted 'on said frame; and' a transmission mechanism connecting said engine and said disk, embodying a pin-wheel, the pins whereof engage and enter said holes in said disk,
